One day. It can fly by with little accomplished but there are a lot of things that happen every 24 hours on Earth. Even if you don't manage to get out of bed, the world continues to turn and life goes on.

Every person blinks somewhere from about 12,000 to nearly 30,000 times a day and their heart beats 100,000 times. The 1.5 gallons of blood in your body circulates about 4,320 times, travelling 12,000 miles. Each day, around 350,000 babies are born. On average, about $2.60 is spent on health per person. In the country that spends the least on health care, Eritrea, about $0.03 is spent per person per day. For the country that spends the most, the United States, the cost balloons to about $23.00. According to the International Business Times, the average American spends around $90 a day in places such as stores, restaurants, and gas stations.

We define our day as 24 hours, the time it takes the Earth to complete one full rotation on it's axis. Sunrise to sunset. Funny thing is, it actually takes our world 23 hours, 56 minutes, and 4.1 seconds to do this.
